I cloned my old 200GB boot drive to a new 4TB NVMe SSD using Rescuezilla. Unfortunately, it formatted the SSD as 200GB, leaving 3.5TB unallocated. I'm trying to merge this unallocated space with the existing partition, but Windows' disk management tool won't let me extend the volume. I also tried MiniTool Partition Wizard, but it didn't work either. What can I do to resolve this?

If you want to merge the unallocated space with your current drive, you may need to delete the partition that was created in that space first. Just remember, any files on that partition will be lost! You can then extend the volume from your main drive there.
Using GParted can also be a great solution if you're comfortable booting from it. It usually allows more flexibility in managing partitions, including merging them.
Have you checked your partition table? It would help to see a screenshot to understand how everything is laid out. Sometimes the issue can be with how the partitions are set up.
I’ve tried going into Disk Management and it doesn't allow me to extend the volume because it's not recognizing the free space as part of the same drive. I’ll check out those bootable tools you mentioned.
Try using a bootable disk management tool like Hiren's Boot CD. It has better options for moving and resizing partitions than the default tools in Windows.
